The U.S. Supreme Court declined Monday to hear the case of a Wisconsin man who was sentenced to six years in prison by a judge who had consulted the results of a risk assessment algorithm.

The man, Eric Loomis of La Crosse, had been charged with five felony counts in a drive-by shooting case in 2013. At his sentencing, the judge told Loomis he was a high risk to his community. He cited Loomis's score on the COMPAS assessment, a software tool used in the state to measure offenders' chances of committing future crimes.

In Loomis's appeal, he argued that the use of the score violated his rights to due process, pointing to the proprietary nature of the COMPAS assessment — it is a product of the for-profit company Northpointe — and the assessment's improper use of gender.

Last July, the state Supreme Court ruled unanimously against Loomis, saying that incorporating gender as a factor in risk assessment promotes accuracy. The court also said that the assessment, if used "properly," does not violate due process.
